Umbraco 17: The Right Moment to Modernise Your CMS Platform

1.1 Long-Term Support and Reduced Risk

Umbraco 17 is a Long-Term Support (LTS) release, built on the latest .NET 10 LTS platform. It comes with years of support and security updates, giving you a stable foundation until around 2028.

What this means in practice:

• Fewer emergency upgrades and “we need to fix this now” situations

• Predictable security posture for the coming years

• A clear roadmap: you know which platform you’re on, and for how long

If you stay on older versions, the opposite happens: more unplanned work, higher security risk, and technical debt that becomes expensive to fix.

1.2 Lower Technical Debt, Fewer Surprises

With Umbraco 17, several legacy pieces are phased out in favour of a modern, cleaner stack:

• A modern backoffice that is easier to maintain and extend

• A fully current .NET foundation for performance and cloud readiness

• A release cadence designed for incremental improvements, not big shocksumbraco.com

The business effect:
You upgrade once, and avoid another major rebuild for years—while staying inside Umbraco’s official support window.

2.1 For Content & Marketing

Your editors and marketers get a cleaner, faster editing experience designed to reduce errors and speed up publishing.

In day-to-day work, that looks like:

• Easier scheduling and clearer previews

• Less time hunting for content and more time producing it

• A backoffice that feels modern and familiar, not “legacy”

Result:
More campaigns live on time, fewer mistakes, happier editors.

2.2 For IT & Operations

IT and operations teams care about stability, monitoring, and cost. Umbraco 17 helps here too:

• Better support for load-balanced setups and high traffic

• A modern .NET runtime that can reduce hosting and infrastructure costs

• A clearly supported version that fits your security and compliance requirements

Result:
Fewer firefights, fewer late-night deployments, more predictable operations.

Alongside Umbraco 17, Umbraco is rolling out the MCP Server (Model Context Protocol) — a secure way for AI tools to understand and interact with your Umbraco installation through the Management API.

In business terms, this means your CMS can:

• Allow trusted AI copilots (like Claude, GitHub Copilot, or internal assistants) to safely read your site structure, content and media

• Automate editorial housekeeping: find outdated content, spot broken links, suggest improvements

• Support governed content operations, where AI works inside your existing permission model instead of bypassing it

You get the upside of AI without creating a “shadow system” outside your CMS.

At Flowcourier, this is exactly where we sit: we’re Azure and Microsoft-stack specialists who design controlled, secure AI workflows—not experiments that bypass your governance model.

Traditional CMS upgrades often feel like a gamble:

• Hard to estimate

• Hidden complexity in custom code and packages

• Fear of downtime or broken features

We’ve redesigned the upgrade process so you get clarity first, then action.

Step 1 – Assessment & Roadmap

We start with a structured technical assessment of your current Umbraco solution:

• Inventory of integrations, custom code, and packages

• Risk and compatibility overview

• Clear plan: what stays, what needs adjustment, what we modernise

Output:
A short, readable report and a fixed-price proposal, so you can make a decision with confidence.

Step 2 – Guided Upgrade to Umbraco 17

We handle the upgrade in a controlled way:

• Database and schema upgrade

• Package and extension updates or replacements

• Performance and security hardening aligned with your hosting setup

Throughout the project we work the way we always do at Flowcourier:
clear milestones, no drama, and minimal disruption to your team.

Step 3 – Testing, Stabilisation & Handover

Before anything goes live, we:

• Run regression and smoke tests on key user journeys

• Validate editorial workflows with a small group of your users

• Plan a deployment window that fits your business, with rollback options

Result:
A smooth cutover, typically with only a brief content freeze rather than prolonged downtime.

From a budget perspective, the question isn’t “can we delay this?”, but “what does waiting actually cost?”

Upgrading to Umbraco 17 now can:

• Reduce security and compliance risk across the next 3 years

• Cut infrastructure and maintenance costs through a modern .NET foundation

• Increase editor productivity and campaign throughput

• Prepare your CMS for governed AI and automation via MCP Server

Delaying tends to mean:

• Paying for emergency fixes on an ageing platform

• Losing time to manual editorial and operational work that could be automated

• Having to jump multiple versions later, under more pressure and higher cost

When you work with Flowcourier on your Umbraco upgrade, you’re not just buying “hours of development”:

• Architecture & governance first – we design with long-term stability and digital sovereignty in mind.

• Project delivery discipline – clear scope, milestones, and communication; on time and on point.

• Automation & CRM experience – we know how your CMS fits into the wider stack: CRM, membership, payments, analytics and automation.

Our role is to make this upgrade a managed business change, not a risky IT bet.

If you’re on older Umbraco you’re in the perfect spot to move to 17 with a clean, supported path.

We offer a free Umbraco 17 Readiness Review, where you’ll get:

• A quick technical scan of your current solution

• A view of package and integration readiness

• A proposed upgrade approach, timeline, and commercial model

No commitment, no pressure—just clarity on your options.
